Overview
LPC1114-LCD is an open-source printed circuit board by MarceloSalazar, from the MarceloSalazar/LPC1114-LCD repository on GitHub, published under the MIT licence. It is a 2-layer board of 80 × 52 mm with 59 parts on 68 nets, routed with 572 tracks and 54 vias.
It is built around the CH340C, DS3231MZ+ and USBLC6-2SC6, with the XC6206P332MR-G, B5819W and SS8050 among its other parts. Its parts include 16 resistors, 10 capacitors, 6 diodes, 5 ICs and 5 switches. It belongs with the lEDs and displays boards and the NXP (LPC, Kinetis, i.MX RT) boards of this library.

Flujo de trabajo
-
Edita el esquemático y el PCB en KiCad.
-
En el PCB: Herramientas → Actualizar PCB desde el esquemático (F8) y vuelve a rellenar las zonas (B).
-
Ejecuta el script desde la raíz del repositorio:
powershell powershell -ExecutionPolicy Bypass -File hardware\scripts\export_fab.ps1El script se detiene si el ERC o el DRC encuentran errores. Si todo es correcto, regenera
fabrication/LPC1114-LCD_JLCPCB.zip, la BOM y la CPL de JLCPCB, la lista de soldadura manual, el STEP, el PDF del esquemático y los renders dedocs/images.
Campos de los símbolos
LCSC: código de la pieza en JLCPCB/LCSC. Los símbolos que lo tienen los monta JLCPCB y entran en la BOM y la CPL de PCBA.Assembly = USER: componentes que se sueldan a mano (U1, DS1, RV1, BZ1, U5, J2, J3).- DNP (atributo Do Not Populate y
Assembly = DNP ...): RTC opcional U4, C9 y BT1 en la cara inferior. No entran en la BOM ni la CPL de JLCPCB; el script los lista enfabrication/LPC1114-LCD_DNP_options.csv.

Questions
How big is the LPC1114-LCD PCB?
It measures 80 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LPC1114-LCD use?
59 parts, built around the CH340C, DS3231MZ+, USBLC6-2SC6 and XC6206P332MR-G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LPC1114-LCD KiCad files?
From the MarceloSalazar/LPC1114-LCD repository on GitHub, at the commit this page was made from: the board is hardware/LPC1114-LCD.kicad_pcb and its schematic hardware/LPC1114-LCD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LPC1114-LCD design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
